I am having trouble with this question.

The BMW 650i Cabriolet sells for $131,080 (tax included). BMW financial services offers a five (5) year loan (with monthly payments) and the option of a final "balloon" payment at the end of the five year term. BMW charges 2.0% per annum. How big does the balloon payment have to be in order for your monthly payments to be $1,000?

A) $81,206

B) $81,406

C) $81,606

D) $81,806

E) $82,006
